Vent Termination
This unit has been equipped with an integral venting
system and designed to operate only with this venting
system. No additional venting shall be used. This unit
must be vented to the outdoors.
WARNING:
This unit is intended for outdoor installation
only. Do not vent the unit through a conventional
venting system.
A vent cover assembly has been supplied with the unit
and can be found secured to the gas controls within
the control area of this unit. Figure 2 shows the proper
installation of the vent cover assembly over the vent outlet
on the exterior of the corner panel. The fasteners used to
secure the vent cover assembly have been included in
the owner’s package.
The vent cover assembly must
be installed to assure proper operation of the unit.
The following list summarizes the requirements for the
location of the vent system termination:
• The location of the vent termination must be consistent
with the National Fuel Gas Code (ANSI Z223.1) or
CAN/CGA-B149 Installation Codes.
• The vent termination must be located at least 4 feet
horizontally from any electric meters, gas meters,
regulators, and relief equipment.
• The vent termination must be located at least 3 feet
above any forced air inlet located within 10 feet.
• The vent termination must be located at least 4 feet
below, 4 feet horizontally from, or 1 foot above any
door, window, or gravity air inlet into any building.
• The vent termination must be located at least 1 foot
above grade.
• The unit should be installed in a way that prevents any
obstruction of the vent termination during accumulating
snow.
General Information
WARNING:
Installation methods other than those described
in the following sections must comply with the
National Fuel Gas Code and all applicable local
codes for providing sufficient combustion air
to the furnace.
Provisions must be made during the installation of this
unit that provide an adequate supply of air for combustion.
• Instructions for determining the adequacy of an
installation can be found in the current revision of the
NFGC (ANSI Z223.1 / NFPA54). Consult local codes
for special requirements
. These requirements are for
US installations as found in the NFGC.
• The requirements in Canada (B149.1) are structured
differently. Consult with B149.1 and local code officials
for Canadian installations.
WARNING:
Combustible air must not be drawn from a
contaminated atmosphere. Excessive exposure
to contaminated combustion air will result in
safety and performance related problems.
To maximize heat exchanger life, the combustion air
must be free of chemicals that can form corrosive acidic
compounds in the combustion gases. The recommended
source of combustion air is to use clean air from outside.
DO NOT place any chemicals with flammable or caustic
vapors or these other corrosive chemicals near the
vent termination:
• Gasoline/Kerosene
• Permanent wave solutions
• Chlorinated waxes and cleaners
• Chlorine based swimming pool chemicals
• Water softening chemicals
• De-icing salts or chemicals
• Carbon tetrachloride
• Halogen type refrigerants
• Cleaning solvents
• Cements, glues, paint removers, varnishes, etc.
• Hydrochloric acid
• Masonry acid washing materials
• Plumbing Stack
Air openings in the door of the unit, warm air registers, and
return air grilles must never be restricted. If the unit does
not receive an adequate supply of air for combustion, the
flame roll-out control located above the burners will open,
turning off the gas supply to the burners. This safety device
is a manually reset switch.
IMPORTANT NOTE : DO NOT install jumper wires across
this control to defeat its function or reset the control
without identifying and correcting the fault condition .
If this control must be replaced, use only factory authorized
replacement parts. See the Replacement Parts List on
page 22.
